How to set default values for respondents?

With types of questions the 'categories – single answer', 'categories - multiple answers' and 'table - classic' default value can be set in the 'Advanced' tab in the editor, where you select the default answer from the 'Preset value' list.

This functionality is especially useful for different types of forms and confirmations where we assume that the most respondents will choose the same answer (such as 'I confirm my participation').
